That 40 A is continuous across the full 0…40 A range with natural convection up to +60 °C; above that it derates 2%/K to +70 °C, so at +65 °C the usable current drops to 36 A. For a control cabinet with multiple PLC racks, DC motor brakes, and solenoid banks, this supply covers the 24 V bus without oversizing. ## DIN-rail fit and airflow clearance Snaps directly onto DIN rail EN 60715 35×15 — no mounting plate or adapter. The bottom clearance is 50 mm and top clearance is 50 mm; left/right clearance is 0 mm, so adjacent devices can butt up against the sides. The 50 mm top gap is the critical airflow path for natural convection cooling — respect it in the layout or the derating curve shifts. ## Approvals and compliance — UL, CSA, CE, EAC UL-Listed under UL 508 (File E197259) and CSA certified to C22.2 No. 14 and C22.2 No. 107.1. CE marked and EAC approved — the supply ships into North American, European, and Eurasian Economic Union panels without additional certification paperwork. Galvanic isolation meets SELV per EN 60950-1 and EN 50178.","metaTitle":"Siemens 6EP1437-3BA00 DIN Rail Power Supply, 40 A, 24 VDC","metaDescription":"Siemens 6EP1437-3BA00 DIN Rail Power Supply, 40 A output, 24 VDC, UL/CSA listed, IP20, active production.
